[0050] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0051] Embodiment 1:

[0052] In view of the problem that the transfer vehicle in front of the furnace in the prior art can only transfer one molten iron ladle at a time and the transfer method is inefficient, this embodiment improves the transfer vehicle, and the specific solution is as follows.

[0053] like Figure 1-Figure 4 As shown, the double-station transfer vehicle of this embodiment is used to transfer molten iron in front of a melting furnace, including a walking base 1 located in front of the melting furnace and walking along the arrangement direction of the melting furnace, and also including a first ladle support seat 2 and a second ladle support seat 3 arranged side by side on the walking base 1 along the arrangement direction of the melting furnace. The first ladle support seat 2 and the second ladle support seat 3 have the same structure, and the structure of the second ladle support seat 3 includes:

[0054] A bearing seat body 31, the bearing seat body 31 is slidably mounted on the walking base 1, the sliding direction of the bearing seat body 31 is perpendicular to the walking direction of the walking base 1, and the bearing seat body 31 is used to place the molten iron ladle;

[0055] The driver 32 is installed on the walking base 1 and is in driving connection with the bearing base 31 , and is used for driving the bearing base 31 to slide relative to the walking base 1 toward and away from the melting furnace.

[0056] Further, if Figure 2-Figure 3 As shown, the structure of the walking base 1 is: a frame 11, a plurality of wheels 12 are installed on the frame 11, the wheels 12 cooperate with the track in front of the melting furnace, a walking motor 13 is installed on the frame 11, and also includes a transmission shaft 14, the walking motor 13 is connected to the transmission shaft 14, and the two ends of the transmission shaft 14 are respectively connected to two wheels 12, and the two wheels 12 are located at one end of the walking base 1 in the traveling direction.

[0057] Specifically, there are four wheels 12. The output shaft of the travel motor 13, the transmission shaft 14 and the two wheels 12 are connected by a tightening sleeve. The travel motor 13 is used as a drive to drive the travel base 1 to move along the track in front of the melting furnace.

[0058] Further, if Figure 2-Figure 4 As shown, the driver 32 is a motor, and a gear 3201 is installed at the output end of the driver 32. A guide rail 3102 and a rack 3101 meshing with the gear 3201 are provided on the supporting seat body 31. The length directions of the guide rail 3102 and the rack 3101 are consistent. A plurality of rollers 15 are installed on the walking base 1, and the plurality of rollers 15 are slidably connected to the guide rail 3102.

[0059] The double-station transfer vehicle of this embodiment is in the continuous working process (the melting furnace in this embodiment is an electric furnace):

[0060] When the track cannot get close to the electric furnace, the walking base 1 moves in front of the electric furnace, and the driver 32 starts the first ladle support 2 to drive the ladle to move forward and backward. After the landing point requirement of the molten iron parabola is met, the molten iron in the electric furnace is poured into the ladle on the first ladle support 2;

[0061] The molten iron bag on the first molten iron ladle support seat 2 is full of molten iron, and at this time, there is no molten iron bag on the second molten iron ladle support seat 3, and the walking base 1 moves to another station and docks with the intermediate transfer vehicle;

[0062] The empty ladle on the intermediate transfer vehicle is transferred to the second ladle support 3, and then the ladle filled with molten iron is transferred from the first ladle support 2 to the intermediate transfer vehicle;

[0063] Then the walking base 1 moves to the next electric furnace and repeats the above-mentioned action.

[0064] The double-station transfer vehicle of this embodiment improves the transfer efficiency of molten iron in a relatively economical manner without modifying the relevant structures of the electric furnace and without adding intermediate transfer vehicles.

[0065] By arranging two ladle supports side by side along the arrangement direction of the melting furnace, and slidingly installing the ladle supports on the walking base 1, the driver 32 is used to drive the ladle supports to approach and move away from the melting furnace, thereby greatly shortening the switching time interval between the empty ladle and the full ladle, and when the track cannot be laid close to the electric furnace, the ladle can be moved toward the electric furnace to ensure that the molten iron in the electric furnace can be directly poured into the ladle, thereby improving the transportation efficiency of the molten iron in an economical and convenient way.

[0066] Embodiment 2:

[0067] In the prior art, when adding inoculant into the molten iron ladle, it needs to be thrown in manually, which is a cumbersome process with high labor intensity, and affects the production rhythm, causing instability of the production rhythm. In view of this problem, this embodiment adds an automatic inoculant feeding mechanism 4 on the basis of the first embodiment, and the specific scheme is as follows:

[0068] like Figure 1-Figure 6As shown, the double-station transfer vehicle of this embodiment also includes an inoculant automatic feeding mechanism 4, which is composed of two sets, corresponding to the first ladle support seat 2 and the second ladle support seat 3 respectively. The structure of the inoculant automatic feeding mechanism 4 is:

[0069] It includes a bracket 41 fixedly mounted on the bearing seat body 31, a rotating rod 43 is rotatably mounted on the bracket 41, a hopper 42 is mounted on the rotating rod 43, and the hopper 42 is used to contain the inoculant;

[0070] A rotation drive mechanism 44 is also mounted on the bracket 41 , and the rotation drive mechanism 44 is in transmission connection with the rotating rod 43 . The rotation drive mechanism 44 is used to drive the rotating rod 43 to rotate and thereby dump the inoculant in the hopper 42 into the molten iron ladle.

[0071] An automatic inoculant feeding mechanism 4 is arranged on the double-station transfer vehicle. After the molten iron is poured into the ladle, the inoculant is automatically added to the molten iron, so as to realize the automation of the process, improve the efficiency, make the production rhythm controllable, and reduce the labor intensity.

[0072] Further, if Figure 4-Figure 6 As shown, the structure of the rotation drive mechanism 44 is:

[0073] It includes a telescopic cylinder 4401 mounted on a bracket 41, and a rotating member 4402 fixedly mounted on the end of a rotating rod 43;

[0074] One end of the telescopic cylinder 4401 is hinged to the bracket 41, and the hinge position is the first hinge part. The other end of the telescopic cylinder 4401 is hinged to one end of the rotating member 4402, and the hinge position is the second hinge part. The axis of the first hinge part, the second hinge part and the axis of the rotating rod 43 form a triangle.

[0075] Specifically, the telescopic cylinder 4401 is a hydraulic cylinder, and a rocker structure is used to convert the linear drive of the telescopic cylinder 4401 into the rotation of the rotating rod 43, which has a simple structure and low cost.

[0076] Further, if Figure 1 , Figure 4 As shown, the bracket 41 is gate-shaped, and the two brackets 41 span over the first ladle support 2 and the second ladle support 3 respectively.

[0077] like Figure 4 As shown, the bearing seat body 31 includes a frame 3103, on which a plurality of rollers 3105 are rotatably mounted side by side, and the plurality of rollers 3105 are used to bear the molten iron ladle;

[0078] A transmission motor 3104 is installed on the frame 3103, and the transmission motor 3104 is in transmission connection with the roller 3105, and the rolling direction of the roller 3105 is consistent with the sliding direction of the bearing seat body 31;

[0079] like Figure 5 , Figure 6 As shown, there are two stations for placing ladles along the arrangement direction of the multiple rollers 3105, and the bracket 41 is located on the frame 3103 between the two stations. The two stations are a station for pouring inoculant corresponding to the hopper 42, and a station for pouring molten iron corresponding to the melting furnace.

[0080] like Figure 4 As shown, a weighing sensor 3106 for measuring the change in the mass of molten iron in the ladle is installed on the bearing seat body 31.

[0081] Specifically, a roller seat 3107 is installed on the frame 3103, and a roller 3105 is rotatably installed on the roller seat 3107. There are four weighing sensors 3106 located at four corner positions of the roller seat 3107 respectively. The weighing sensors 3106 connect the frame 3103 and the roller seat 3107 to measure the mass change of molten iron in the ladle.

[0082] The powered roller type bearing seat body 31 can drive the molten iron ladle to move relative to the bearing seat body 31, and switch between the pouring inoculant station and the pouring molten iron station.

[0083] When the bracket 41 is located on the frame 3103 between the two stations, the automatic inoculant feeding mechanism 4 is moved away from the melting furnace to avoid the molten iron parabola, and the pouring direction of the hopper 42 is away from the melting furnace. The molten iron ladle is added with inoculant at the pouring inoculant station, such as Figure 6 As shown, this workstation also facilitates the intermediate transfer vehicle to transport the ladles.

[0084] Specifically, the capacity of the hopper 42 is ≥ 4 kg of inoculant. When producing gray iron, the inoculant is automatically added when 1 / 3 of the molten iron is discharged. The feeding frequency is 1 time / bag. The control system of the double-station transfer vehicle can select the function of adding inoculant according to the specific situation. The function may include three modes: automatic / manual / none.

[0085] The weighing sensor 3106 provides real-time feedback on the mass changes of the molten iron in the ladle, and is used to monitor whether the amount of molten iron in the ladle has reached the weight required for adding the inoculant, thereby controlling the time point for adding the inoculant.

[0086] Two stations for placing molten iron ladles are arranged on the bearing seat 31, and a powered roller-type bearing seat 31 is adopted, and the automatic inoculant feeding mechanism 4 is arranged between the two stations to avoid the molten iron pouring path and facilitate the docking of the double-station transfer vehicle with downstream equipment.

[0087] Embodiment three:

[0088] In order to prevent smoke and dust from escaping from the molten iron ladle during the transfer of molten iron, causing indoor environmental pollution and causing nearby workers to be exposed to or inhale dust, resulting in physical discomfort and harm to the body, a dust removal system is added on the basis of the above embodiment.

[0089] like Figure 1 , Figure 7 As shown, it also includes a ladle cover 5 matched with the ladle, and a ladle cover driving mechanism 6 installed on the walking base 1 between the first ladle support 2 and the second ladle support 3, and the ladle cover driving mechanism 6 is used to drive the ladle cover 5 to rise, fall and rotate;

[0090] A collecting chamber is arranged on the ladle cover 5, and a dust removal device 7 is also arranged on the walking base 1. The dust removal device 7 is connected with the collecting chamber and is used to collect smoke and dust in the ladle.

[0091] Specifically, the number of the ladle cover 5 is one, and the position of the ladle cover 5 is switched by a rotation drive method, thereby reducing the complexity of the structure of the double-station transfer vehicle and the manufacturing cost. When the ladle is filled with molten iron, the ladle cover driving mechanism 6 drives the ladle cover 5 to rotate to the top of the ladle and then drives the ladle cover 5 to descend and cover the ladle, and then the dust removal device 7 is started to collect the smoke and dust in the ladle.

[0092] The ladle cover 5 does not interfere with the automatic inoculant feeding mechanism 4 during the operation. Preferably, two stations for placing the molten iron ladle, namely, a station for pouring the inoculant and a station for pouring the molten iron, are arranged on the bearing seat body 31 .

[0096] Specifically, the seat plate 61 is installed on the frame 11 of the walking base 1, the sleeve 64 is fixed relative to the frame 11, the connecting pipe 65 can move up and down and rotate relative to the sleeve 64, and the two are sealed and connected, and a hole communicating with the sleeve 64 is provided on the connecting pipe 65, and the sleeve 64 is connected to the inlet of the dust removal equipment 7.

[0097] The dust removal device 7 includes a fan 71 and a dust removal component 72. After the fan 71 is started, the smoke and dust in the collection chamber passes through the connecting pipe 65, the sleeve 64, and the cantilever 66 and then enters the dust removal component 72 to be collected.

[0098] The process of receiving and transferring molten iron by the double-station transfer vehicle is as follows:

[0099] The empty ladle is located at the molten iron pouring station, receiving molten iron from the melting furnace. When the amount of molten iron reaches 1 / 3 of the ladle, the pouring of molten iron stops;

[0100] The transmission motor 3104 on the bearing seat body 31 is started, and the empty iron ladle is moved to the inoculant pouring station, and the inoculant automatic feeding mechanism 4 is started to pour the inoculant into the iron ladle;

[0101] Then the transmission motor 3104 is started, and the roller 3105 rotates in the opposite direction, moving the ladle to the pouring station, and continuing to pour the molten iron into the ladle;

[0102] After the molten iron in the ladle is filled, the ladle cover 5 rotates to the top of the ladle and covers the ladle;

[0104] It is docked with the intermediate transfer vehicle, the ladle cover 5 is opened, the transmission motor 3104 is started to move the molten iron ladle to the inoculant pouring station, and the intermediate transfer vehicle takes the molten iron ladle away.
